A lone, masked gunman walked into a restaurant in the 3400 block of W. National Ave. in Milwaukee Saturday night and announced a robbery.

Then, a restaurant employee pulled out a gun and chased the man out of the restaurant, exchanging gunfire in the street, according to Milwaukee police.

The attempted robbery occurred around 8:10 p.m. Police have not identified the suspect, who is at large, but continue to investigate. They have not received reports anyone was injured by the gunfire.

In a separate incident, Milwaukee police responded to a report of child abuse at a home in the 4100 block of N. 24th Place. When they arrived, a male resident of the house threatened to shoot at the officers, according to the statement.

The 23-year-old man's adult girlfriend and a 3-year-old child were in the house with him. MPD crisis negotiators were able to speak with the man on the phone and eventually persuade him to release the child and surrender.

The suspect was taken into custody and faces felony charges of physical abuse of a child, the statement read.
